He's always had something of a talkshow host to him, that set him apart from other heavy metal front men who were more the chest beating type. Halford always has a twinkle in his eye - you have to, given JP's brand of escapist comic strip lyrics populated by sinners, rippers, exciters, hellions, jawbreakers, metallians, sentinels, painkillers and angels of retribution etc. It would be unbearable if he took this stuff serious - you'd be in Manowar territory then.
